"Had basement windows installed. Great job, explained everything. The windows were the original ones. They covered the floors and the basement steps, cleaned up everything afterwards."

"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"Wally and his crew do incredible work, are professional, pleasant and conduct themselves as gentlemen. Wally discovered significant water and termite damage during the onset of a home remodeling project. Wally was transparent, supportive and most of all reliable when giving us options. We're very pleased with the work thus far. Wally has reinstilled my trust in the General Contractor industry. I highly recommend Wally and his team. I plan to utilize their services again in the future once these initial projects are complete."

"Matt and his team with MNB Renovations did a 32 x 24 addition that was basically a home build from the ground up. I am still surprised for the size of this project how stress free the process was. Matt was very detailed and checked in on everything to make sure we were getting what we wanted. In the end he asked us to make a list of anything that needed to be addressed and there was absolutely nothing to mention. They did a perfect job, the quality of the work is amazing, and the entire team was very nice, professional, and trustworthy! I absolutely recommend this company to others and will definitely use them again in the future!"

"We hired Michael Ward to finish our basement including a full bathroom with a walk in shower and closets. Michael was a pleasure to work with. He is a professional, knowledgeable and experienced contractor who takes pride in his work. His prices are very competitive and he completed the entire job at a timely manner. We are very satisfied with the end result. The finished basement looks flawless and the new bathroom is beautiful. I highly recommend Michael and will hire him if I have any other projects in the future."

"this was not a conventional basement remodel... Removed existing drywall walls and ceiling and installed acoustic insulation and acoustic drywall on suspended rails. Renato was knowledgeable, communicative and friendly. His crews did first rate work. I would hire again and certainly recommend him for specialized, acoustic construction!"

FAQs for basement remodeling projects in Unionville, PA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
